Apple was nowhere near a tech giant when the iPhone was introduced. Facebook was a student's project. Consumer tech innovation just doesn't happen in Europe, I think that's the real issue Europe should be tackling, given how influential consumer tech is.
European countries used to have their local Facebooks and Twitters, but they got wiped out once the US companies got better at localizing their services.
Which is not in itself a natural phenomenon - Spotify for example did not get wiped out by Apple Music or Google Play/YouTube Music. Europe's local Facebooks and Twitters just weren't that good.
